Ideas for preference backend

Hi,

Gwen and I are building a preference system for gst.
There is a couple of idea we've wanted to propose you.

1)First question is wether to use a XML, ini .. file or a file containing plain
smalltalk code.

2) If we chose to have a smalltlalk file acting like a ".emacs"  what kind of
"dsl" do you want to see
Proposition 1: a verbose but simple one
PrefConfiguration from: {
        PrefGroup name: 'GTK' with: {
        PrefSection name: 'font' with: {
            PrefValue name: 'size' value: 12.
            PrefValue name: 'style' value: 'italic'
        }.            
        PrefSection name: 'color' with: {
            PrefSection name: 'windows'  with: {
                PrefColorValue name: 'background' value: 'EDE9E3'.
            }
        }
     }
}

Proposition 2: Less but more customizable one:
PrefConfiguration from: {
      'GTK' -> {
           'font' -> {
                'size' -> 12.
                'style' -> 'italic'
        }.            
        'color' -> {
            'windows'  -> {
                'background' -> 'EDE9E3'.
            }
        }
        }
}

Or other idea.

Thanks for your comment or remark.

Either ini or smalltalk.  In the latter case there is already "~/.st/init.st".

Paolo

Two levels only please:

(Smalltalk preferences at: #windows)
    at: #background put: 'EDE9E3'.

or you can even force the first level to be a package.

(PackageLoader packageAt: 'GTK') preferences
    at: #'window-background' put: 'EDE9E3';
    at: #'font-size' put: 12.

Paolo

Every time the interpreter is started.
